The Town of Beech Mountain Collection system reported a Notification of Discharge of
Untreated Wastewater to Pond Creek in Watauga County NC on April 11th and 12th, 2024 of
approximately 50,732 gallons to NCDEQ. The cause of the spill was determined to be an
excessive rainfall event of at lease 2 inches of rainfall during a severe period in the storm
resulting in the inability of the treatment plant to contain the incoming volume.
The 2022 Water and Sewer Rehabilitation Project is underway. This project focuses on the
replacement and rehab as well as many manhole repairs in 17,000 feet of sewer main in the
continuing effort to reduce inflow and infiltration to our system. Project completion is expected
by November 2025.
The Utility continues to plan for future repairs in our system and ask for customer involvement
in reducing SSO volume and the reduction of water getting into the system. Help us to keep the
system free of materials that cause blockages by not dumping debris, fats, oils, or grease into the
system.
To report a sewer spill, please contact the Town of Beech Mountain Emergency Dispatch at
828-387-2342. For questions regarding the Town Utilities programs or additional information
regarding this report, please contact Mr. Daniel Davis, Utilities Director at [phone].
